Measuring Gear: Position Tracking, Maximum Actual Value Exceeded; Drive Encoder: Number Of Pulses Is Not To The Power Of Two; Drive Encoder: Number Of Multiturn Pulses Is Not To The Power Of Two - Siemens Sinamics S120 Diagnostic Manual

Remedy: - use an absolute encoder.
- if necessary, de-select the position tracking (p0411 for the measuring gear, p2720 for the load gear).
- use a Control Unit with sufficient NVRAM.
- Only activate position tracking of the load gear in the same encoder data set if the gear ratio (p2504, p2505), axis
type (p2720.1) and tolerance window (p2722) are also the same.
207556 <location>Measuring gear: Position tracking, maximum actual value exceeded
Message value: Component number: %1, encoder data set: %2
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: When the position tracking of the measuring gear is configured, the drive/encoder identifies a maximum possible abso-
lute position actual value (r0483) that cannot be represented within 32 bits.
Maximum value: p0408 * p0412 * 2^p0419
Fault value (r0949, interpret decimal):
Low word low byte: Encoder data set number
Low word high byte: Component number
See also: p0408 (Rotary encoder pulse No.), p0412 (Measuring gear, absolute encoder, rotary, revolutions, virtual),
p0419 (Fine resolution absolute value Gx_XIST2 (in bits))
Remedy: - reduce the fine resolution (p0419).
- reduce the multiturn resolution (p0412).

Gx_XIST2 (in bits))
207560 <location>Drive encoder: Number of pulses is not to the power of two
Message value: Encoder data set: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: For rotary absolute encoders, the pulse number in p0408 must be to the power of two.
Fault value (r0949, interpret decimal):
The fault value includes the encoder data set number involved.
Remedy: - check the parameterization (p0408, p0404.1, r0458.5).
- upgrade the Sensor Module firmware if necessary
207561 <location>Drive encoder: Number of multiturn pulses is not to the power of two
Message value: Encoder data set: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The multiturn resolution in p0421 must be to the power of two.
Fault value (r0949, interpret decimal):
The fault value includes the encoder data set number involved.
Remedy: - check the parameterization (p0421, p0404.1, r0458.5).
- upgrade the Sensor Module firmware if necessary
